A:AnswerI have not done this, but I have seen youtube tutorials of people who have. some that have to cut and modify parts of the opal ice maker and one that said no modifications needed but I never watched it.

A:AnswerThe pump probably went out which is what happened to mine. According to customer service it a common problem that happens. I returned mine because I felt it was a big investment for the machine to have common known problems and not have a recall to fix them. Customer service will email you instructions on how to reset the pump and it might work or might not.
A:AnswerI have been using combination of distilled water and filtered water from my refrigerator and have had no problems. Bottled water has minerals and can build up and make cleaning machine a little more troublesome
